FIELD

Embodiments of the invention relate to graphical user interfaces (“GUIs”). More particularly, embodiments of the invention relate to controlling application programs.

BACKGROUND

Data processing systems, e.g., desktop computers, laptop computers, personal digital assistants, and the like, use display devices (e.g., computer monitors) to show still and moving images on a screen. Graphical user interfaces are created for a user to interact with a data processing system using various images, e.g., icons, windows, text characters, and other objects. Images shown on a screen of a display device may represent programs, files, folders, or other items, e.g., an application launcher (e.g., a “dock interface”). For example, by positioning a pointer, (“cursor”) to an icon and pressing a mouse button, the user executes a command, opens a file represented by the icon into a window, moves the icon around the display screen, or launches an application program. Typically, a user operates the application program executed by a processor through one or more windows displayed on the screen of the display device.

The docking interface (“Dock” such as the dock displayed on Macintosh computers which run Macintosh OS 10.2 or 10.3 or 10.4, etc.) is a graphical user interface that contains icons for frequently used programs. The Dock may indicate the program's current state (e.g., running or not running). The Dock may indicate the current state of the program by showing a symbol, e.g., an ellipsis, or triangle, below or adjacent its icon if the program is not running and nothing if it is currently running.

Typically, positioning a cursor over the icon in the Dock that represents non-operating application program and pressing the mouse button causes the non-operating application to launch. Typically, positioning the cursor over the icon in the Dock that represents an executing application program and pressing the mouse button brings the executing application program to the front of the screen.

As the performance of data processing systems increases, efficient use of the screen space of the display device becomes important. This is especially important for data processing systems having relatively small screens, e.g., laptop computers and personal digital assistants (PDAs).

SUMMARY OF THE DESCRIPTION

Methods and apparatuses for controlling application programs are described. In one embodiment, a first item and a dock interface having a second item are displayed on a screen space. A selection of the first item received. A proxy of the first item is positioned over the second item. Next, a window is displayed in response to the positioning. An application is executed to display the window.

In at least certain embodiments, a user may drag an icon (e.g., dragging a file's icon) onto an icon of an application program displayed on the dock and, if the application program is not already executing, the drag which cause the application program to be launched and at this point, the user may continue the drag by, for example, positioning the icon over a displayed command interface (e.g., a button or menu item or tab item) of the launched application program and cause the command, represented by the displayed command interface, to be executed by the positioning of the icon, while still continuing the drag, over the displayed command interface.

In another embodiment, synchronizing a first docking interface on a first screen space of a first machine to a second docking interface on a second screen space of a second machine is performed. The first docking interface has an item that identifies a first application supported by the first machine and the second docking interface has another item that identifies a second application supported by the second machine.

Methods and apparatuses for controlling application programs on a screen space of a display device in a data processing system that include dock syncing and dock springing and a system having a computer readable medium containing a program code for controlling application programs on a screen space of a display device that include dock syncing and dock springing are described below. Other methods and other features are also described.

FIG. 1A shows one embodiment of a screen space of a display device of a data processing system to control application programs that involves dock springing. As shown in FIG. 1A, a screen space 101 displays a menu 103, a docking interface 111, and an application window 105. Menu 103 displays identifiers for actions that can be performed when the application program App. 1 is executed, such as “Edit”, “View”, “File”, and the like. Application program window 105 for App. 1 includes one or more items 104 that represent application programs, files, and folders, as shown in FIG. 1A. Typically, the application window is an enclosed, rectangular area on the screen space which can be moved around the screen and can be caused to appear and to be removed by a command from the user. Within different windows, a user can run different programs or display different data. Typically, an application receives a user input through the application window.

An application window may have a variety of characteristics or features including one or more of the following: (a) a moveable and resizable container having borders; (b) scroll controls, such as scroll arrows, to scroll the contents of the window; (c) the window can receive user input such as text entry (e.g. through typing or copying and pasting of text) or cursor entry events (e.g. selection of buttons or commands within a window) or dragging and dropping of an object.

Dock interface 111 can include one or more items representing application programs, e.g., user level applications and system level applications, folders, URLs, and the like. Generally, a dock may be considered a displayed region, on a display device, which includes icons of application programs and possibly icons of user created folders or files, and the like, and those application programs can be launched (or if already executing, have their windows brought to the foreground) by selecting the icon on the dock for one of those application programs. Another example of such a displayed region is the toolbar (or task bar) typically displayed at the bottom of a screen space in a Microsoft Windows operating system (e.g., Windows XP). Yet another example of such a displayed region is a dashboard that may contain such application programs to provide weather information, traffic information, and other useful information. As shown in FIG. 1A, dock interface 111 includes items 113, 115, 116, 117, and 119. For example, item 113 represents an application program 1 (“App. 1), item 115 represents an application program 2 (“App. 2”), item 116 represents an application 3 (“App. 3”), item 117 represents an URL, and item 119 represents a folder. Application programs may be, for example, Word®, Outlook®, Acrobat®, Photoshop®, Finder®, Explorer®, or any other application programs known to one of ordinary skill in the art of data processing systems. In one embodiment, items 113, 115, 116, 117, 119 are images, e.g., icons, texts, symbols, or any combination thereof. Any content, e.g., applications, folders, URLs that is represented by an item displayed the dock interface 111 can be “sprung”. For example, springing of an executing application program causes the application program to appear on the front of screen space 101. For example, springing of the application that is not currently executed causes launching the application. Springing of the content of the dock can be performed by selecting one of the items displayed on the docking interface 111, e.g., by positioning a cursor over the item and pressing or double-pressing a mouse button, or by any other method known to one of ordinary skill in the art of data processing systems.

As shown in FIG. 1A, one of items 104 is selected to become a selected item 109. For example, selected item 109 may represent a file containing a picture, a document, a flowchart presentation, or any other file. In one embodiment, selection of item 109 is performed by positioning cursor 107 over one of items 104. In another embodiment, a user performs selection of item 109 by positioning a cursor 107 over one of items 104 and then pressing a button of a mouse (“clicking”). In an embodiment, a selection of one or more items 104 may be performed by using an audio signal, voice, striking and holding of one or more keys on a keyboard, or by any other mechanisms known to one of ordinary skill in the art of data processing systems. In one embodiment, the selected item 109 has a proxy that can be moved over screen space 101. In one embodiment, the proxy can be created by positioning a cursor over one or the items 104 and pressing the mouse. In another embodiment, the proxy can be created using any other methods known to one of ordinary skill in the art of data processing systems. In one embodiment, an item that is positioned on a desktop of a screen space 101 outside window 405 is selected.

FIG. 9 shows one embodiment of a flowchart of a method to control application programs. Method 900 begins with operation 901 that involves displaying a first item and a docking interface having a second item on a screen space, as described above. Method 900 continues with operation 902 that involves receiving a selection of the first item to create a proxy, as described above. Next, operation 903 is performed that involves positioning the proxy of the first item over (e.g., adjacent to) the second item.

FIG. 1B shows a view similar to FIG. 1A, after positioning proxy 108 of the selected item 109 over item 115. As shown in FIG. 1B, item 115 that represents App. 2 is displayed in Dock 111. In one embodiment, proxy 108 is positioned over item 115 by dragging using cursor 107. For an embodiment, proxy 108 may be positioned over item 115 using, e.g., a voice command, a keypad, or any other methods known to one of ordinary skill in the art of data processing systems. For another embodiment, proxy 108 is positioned at a predetermined distance from item 115. The predetermined distance may be, for example, in the approximate range of 0 to 5 millimeters (“mm”) from item 115.

Referring back to FIG. 9, method 900 continues with operation 904 that involves displaying a window having a third item when a proxy of the first item is positioned over the second item, wherein an application is executing to display the window, as described below. In one embodiment, operation 904 of displaying the window involves launching the application if the application was not executing. In another embodiment, operation 904 of displaying the window involves bringing the window of the executing application, as described in further detail below. In one embodiment, an operation (not shown) is performed that involves determining whether a predetermined amount of time of positioning the proxy of the first item over the second item has expired. If the predetermined time has expired, the application window is automatically displayed. If the predetermined time has not yet expired, the application window is not displayed. In one embodiment, the predetermined amount of time is set by the user.

FIG. 1C shows a view similar to FIG. 1B, after a window 131 of App. 2 is displayed in response to positioning proxy 108 over item 115. App. 2 is executing to display window 131. In one embodiment, displaying window 131 involves launching of the App. 2. In another embodiment, displaying window 131 involves bringing the App. 2 to the front of the screen space, as described in further detail below with respect to FIG. 2.

In one embodiment, window 131 of App. 2 is displayed after determining whether a predetermined amount of time of positioning proxy 108 over item 115 has expired. If the predetermined time has expired, the application window 131 is automatically displayed. If the predetermined time has not yet expired, the application window 131 is not displayed. In one embodiment, the predetermined amount of time is set by the user, and can be in the approximate range of 0-20 seconds.

In one embodiment, positioning of proxy 108 over item 115 includes collecting a first information that is represented by proxy 108 and a second information that is represented by item 115 and then comparing these two informations. If the first information is not compatible with the second information, positioning of proxy 108 over item 115 does not cause displaying window 131. For example, if a type of the file represented by proxy 108 is not compatible with an application represented by item 115, positioning of proxy 108 over item 115 does not cause displaying window 131.

As shown in FIG. 1C, a menu 124 that contains one or more items representing functions that can be performed by App. 2 is displayed on screen space 101. Window 131 contains one or more items 132. Each of the items 132 represents an action that can be performed by App. 2. In one embodiment, items 132 represent a default action that can be performed by App. 2. For example, items 132 can represent an action to open a new document, open an existing document, saving a document, and any other action depending on the program application. For one embodiment, items 132 may represent controls of the data processing system. As shown in FIG. 1C, one of items 132 is selected to become a selected item 123. For example, selected item 123 can represent a command to open anew document. In one embodiment, a user performs selection by continuing to position a proxy 108 over one of items 132 to create a selected item 123. In another embodiment, proxy 108 is positioned at a predetermined distance from one of items 132 to create a selected item 123 In one embodiment, continuing of the positioning of proxy 108 over one of items 132 is performed by continuing to drag proxy 108 over one of items 132 to create selected item 123. In another embodiment, continuing of the positioning of the proxy 108 over one of items 132 is performed using an audio signal, voice, striking and holding of one or more keys on a keyboard, or by any other mechanisms known to one of ordinary skill in the art of data processing systems. Referring back to FIG. 9, method 900 continues with operation 905 that involves continue to positioning the proxy of the first item over the third item, as described above. Next, an action that corresponds to the third item is performed at operation 906. In one embodiment, an operation is performed (not shown) that involves determining whether a predetermined amount of time of positioning of the proxy of the first item over the third item has expired. If the predetermined time has expired, the action is automatically performed. If the predetermined time has not yet expired, the action is not performed. In one embodiment, the predetermined amount of time is set by the user.

FIG. 1D shows a view similar to FIG. 1C, after displaying a new document window 106 in response to positioning proxy 108 over selected item 123 or at a predetermined distance fro selected item 123. That is, positioning of a proxy over a visual interface, e.g., selected item 123, or at a predetermined distance from the visual interface causes actuation (springing) of this visual interface (e.g., selected item 123). In one embodiment, springing an application from dock 111, and springing (actuation) of the visual interface (e.g., menu items, buttons, and other controls) involves continuously dragging of the proxy of a selected object over a selected icon in dock 111 and over selected visual interface through the entire sequence with a single click of the mouse button.

In one embodiment, displaying new document window 106 is performed after proxy 108 is positioned over selected item 123 for a predetermined amount of time, e.g., in the approximate range of 0 to 50 seconds. In one embodiment, the predetermined amount of time is set by the user.

FIG. 1E shows a view similar to FIG. 1D, after proxy 108 of the item 109 positioned into document window 136 is released. In one embodiment, proxy 108 can be released by releasing the mouse button. For another embodiment, proxy can be released using, a voice command, a keypad, or any other methods known to one of ordinary skill in the art of data processing devices. As shown in FIG. 1E, document window 106 contains a document 136. As shown in FIG. 1E, a picture 125 is inserted into document 136.

FIG. 10 shows a flowchart of another embodiment of a method to control application programs. Method 1000 begins with operation 1001 that involves displaying a first window having a first item and a dock having a second item on a screen space, wherein a first application is executing to display the first window. Next, a selection of the first item is received in operation 1002. Further, operation 1003 that involves dragging a proxy of the first item along the screen space to position over the second item is performed. Next, displaying a second window having a third item when the proxy of the first item is dragged over the second item is performed. A second application is executing to display the second window. Next, operation 1005 that involves dragging the proxy of the first item to position over the third item is performed. Further, operation 1006 is performed that involves displaying a third window on the screen space when the proxy of the first item is dragged over the third item. The third window is displayed in response to performing a default function represented by the third item. Operations 1001-1006 were described above. Next, a determination is made at operation 1007 whether the first item is a proper item. If the first item is a proper item, the proxy of the first item is dropped into the third window in operation 1008. If the first item is not a proper item, the proxy of the first item is positioned outside the third window. Next, the third window is removed from the screen space in operation 1010 in response to positioning the proxy of the first item outside the third window. In one embodiment, dragging of the proxy of the first item is performed continuously with a single pressing (“click”) of the mouse button throughout the entire sequence of operations 1003-1008 or the entire sequence of operations 1003-1010.

FIG. 1F shows a view similar to FIG. 1D, after proxy 108 is positioned outside application window 106. In one embodiment, proxy 108 is positioned outside application window 106 by continuing to drag proxy 108 using cursor 107.

FIG. 11 is a flowchart of one embodiment of a method to control application programs that includes dock syncing. Method 1100 begins with operation 1101 that involves displaying a first docking interface on a first screen space of a first machine, wherein the first docking interface has a first item, wherein the first item identifies a first application. Next, operation 1102 that involves displaying a second docking interface on a second screen space of a second machine, wherein the second docking interface has a second item, wherein the second item identifies a second application is performed, as described above with respect to FIG. 6. Next, operation 1103 is performed that involves synchronizing the first docking interface and the second docking interface. Dock syncing is a process of making the docking interfaces on multiple machines the same. Synchronizing of the items of the docks ensures that the content of a user's dock, e.g., applications, folders, documents, URLs, and the like, is updated to be the same as the content of the Dock's of other machines that are coupled to the user's machine over a network.

In one embodiment, synchronizing a dock of a machine to another dock of another machine is performed periodically over a period of time. In another embodiment, synchronizing of a dock of a machine to another dock of another machine is performed per a request of a user of the machine. In one embodiment, the priority of syncing the dock of a machine to another dock of another machine is determined by a user of the machine. Next, operation 1104 is performed that involves determining whether the first machine supports the second application. If the first machine supports the second application, the second item is added to display on the first docking interface in operation 1105. If the first machine does not support the second application, the second item is not added to be displayed on the first docking interface in operation 1106. Method continues with operation 1107 that involves determining if the second machine supports the first application. If the second machine supports the first application, the first item is added to display on the second docking interface in operation 1109. If the second machine does not support the first application, the first item is not added to display on the second docking interface in operation 1108.

After synchronizing 608 has been performed, item 614 representing App. 1 is displayed on dock 603, and item 613 is displayed on dock 604, so that content of both docks 603 and 604 is updated to be the same, as shown in FIG. 6. In one embodiment, a position of item 613 within docking interface 603 after syncing is the same as a position of item 613 within docking interface 604. In another embodiment, a position of item 613 within docking interface 603 after dock syncing is adjusted depending on a position of another item 614 within docking interface 604. In one embodiment, items 611-614 are reordered after dock syncing 608. In one embodiment, after dock syncing 608, a display order of items 611-614 is modified such that items 611-614 are displayed in the same order on all machines. In another embodiment, the display order of items 611-614 is modified such that items 611-614 have different display order on the machines according to user preferences.

FIG. 12 is a flowchart of another embodiment of a method to control application programs that includes dock syncing. Method 1200 begins with operation 1201 that involves adding a first item to a first dock of a first machine, wherein the first item identifies a first application. Next, operation 1202 of synchronizing of the first machine is performed. In one embodiment, synchronizing of the first machine is performed using MAC OS X (“Trademark”) Sync Services provided by Apple Computer, Inc located in Cupertino, Calif.

In one embodiment, synchronizing from the first machine to a second machine that has a second dock is performed. Next, operation 1203 is performed that involves synchronizing the second machine having a second dock with the first machine. Next, opera ion 1204 that involves determining whether the second machine support the first application is performed. If the second machine supports the first application, the first item is displayed on the second dock of the second machine in operation 1205. If the second machine does not support the first application, the first item is recorded as “missing item” and is not displayed on the second dock in operation 1206. Further, if the synchronizing is performed back from the first machine to the second machine in operation 1207, the first item is not modified on the dock of the first machine in operation 1208. As such, the first machine does not know that the first item is “missing” from the second dock, so the first item is not removed from the first dock after synchronizing back the first machine to the second machine. That is, the respective docks of multiple machines having disparate applications can be still synced without a fear of dock data loss. Methods described above with respect to FIGS. 11 and 12 can be performed for synchronizing dashboard interfaces of a plurality of machines that support disparate application.

For example, a user adds a new application 613 (e.g., TextEdit) to dock 603 of Machine 1. Next the user syncs Machine 1 over a network. Next, when machine 2 performs synchronizing over the network, new application 613 is displayed on dock 604, as shown in FIG. 6.

FIG. 7 shows one embodiment of a data processing system to control application programs that includes dock syncing. As shown in FIG. 7, the data processing system 700 includes Machine 1 and Machine 2. Machine 1 has a display device with a screen space 701 and Machine 2 has a display device with a screen space 702.

As shown in FIG. 7, screen space 701 displays a dock 703, and screen space displays a dock 704. Each of dock 703 and dock 704 has one or more items 705 representing application programs, e.g., user level applications and system level applications, folders, URLs, and the like. As shown in FIG. 7, dock 703 includes items 711, 712, 713, and 715 and dock 704 has items 711, 712, and 714. For example, item 711 represents an URL, item 712 represents a folder, item 713 represents an application program 1 (“App. 1), item 714 represents an application program 2 (“App. 2”), and item 715 represents an application program 3 (“App. 3”), e.g., Adobe Photoshop®. In one embodiment, items 705 are images, e.g., icons, texts, symbols, or any combination thereof. In one embodiment, App. 1, App. 2, and App. 3 are supported by Machine 1. Machine 2 supports App. 1 and App. 2, but does not support App. 3.

After syncing 708 has been performed, contents of both docks 703 and 704 are updated, as shown in FIG. 7. As shown in FIG. 7, items 711-715 that are supported by Machine 1 are displayed on dock 703, and items 711-714 that are supported by Machine 2 are displayed on dock 704. Item 715 that is not supported by Machine 2 is not displayed on dock 704.
